Paint composition.

No Drawing. v To all who m it mag concern: I

[a citizen of;the United States, residing at Atlanta, in the county of Fultonyand State of Georgia, have invented certain new and useful Improvements in Paint Compositions, of which the following is a specification.

This invention comprehends certain new and useful improvements in paint compo sitions, and has for its primary ob ect 'to provide certain improvements in the com-' position for which I obtained Letters Patent.

of theUnited States, No. 1,091,309, issued' March "24, 1914; t

' The-patented print composition embodies the characteristic of capability of resisting the. action of the elements, both air and Water, and has been foundpiarticularly dc sirable and effective asa coating or imp-regnating fluid for; roofs and bridgesorJwherever it is desired to preserve any structures, especially those that are exposed; and,the present invention aims to still further improve'the .compo'sitionby the addition: of ingredients for the purpose of bringing out slateiand brown colors-and to further increase the lasting qualities of the paint, With this andother objects in view, as will more fully appear as the, description proceeds, the invention consists-in apaint composition composed,'in addition to-the ingredients embodied in the originally patented paint composition,'o f the following ingredients, namely, ground slate ground in linseed oil and pine tar, preferably North Carolina pine tar. In other words, the com, position as improved, willconta-in the" fol: lowing" ingredients herei'nbelow named and mixed substantially in or about the proponti'ons specified, namely,

In addition to the foregoing, I -'a-lso add twenty" pounds of groundslate ground in linseed oil, and-ten gallons, of

gallons of spirits of turpentine for a drier North Carolina'pine tar. While the body ,of the paint is yet warm, these other ingredients are thoroughly mixed therewith and ground together, which will make the composition ready for use in connection with all as for other work generally. s Whlle my improved paint composition is primarily designed for I use on roofs .and

manner of roofing and bridgework, as well,

bridges, I have clearly demonstrated that 7 y it is also effective on the hulls or bottoms of marinevessels, as it is'imperviou's to salt or;

fresh water, and that it is useful not only for: iron and steel bridges, but wooden bridges, posts, or any-part which it isfdesired to maintain ina good state of preservjation' after being' partially or entirely buried in the; gg'round. It willbe found'to be absolutely wlater-proofi'and by the use of 1, the ground slate and'pine tar, above referred to, the desired slate and brown colors Will I be iproprly, brought out while at the same v time not only are thedesired perfect colors obtained, -.bi'1t thelasting. qualities of the composition are increased.

. -While the tars in their crudeform liave heretofore been 'considered'somewhat inju- 'rious, especiallyto metal roofing, I have .i-found that by distilling out the imperfections, as hereinbefore described,.the paint will be as harmless as any oil paint which hasjbeen produced, while my experience has at the same time shown that the great body and durabilityinherent in these tars, makes them a. peculiarly good body with which and oilof tar, said body being mixed with graphite, linseed oil, yellow ocher, oxid'of lons, :mixed with iron, spirits of turpentine, ground slate and pine tar.
